well? what rods did you use? how do they feel? did they make a big difference?
I used some scrap metal from the junk yard and it work great, just that it makes a pinging sound, haha
just joking man. You could use your stock rods but they have to be machined. Performance is the same but it depends on the piston. Try type R rods for better performance and strength later

Why would performance be the same, wouldn’t using gsr pistons raise the CR of a b18a motor. By slugs we’re talking about pistons right?

Yup.

I was talking about ls rods and gsr pistons. Sorry if I didn’t make it clear enough but the ls rods would not make a difference. Well yes if you use gsr pistons then the cr would go up.
G2guru mentioned once upon a time (when I asked him about his gsr rods & pistons for sale) that gsr rods & pistons will lower the CR in an LS. Any comments?
well i have USDM ITR PISTONS IN w/LS rods…feels good…did i mention 14.9 secs 1/4 mile non vtec…stage 3 clutch and cai/jdm itr 4-1 h/ex digital ignition w/ iridium plugs w/ magnecore wired 8mm…much said…

i think that’s 'cause the gsr rods are shorter than the ls rods

Or not. crvtec.com says the gsr rods are .9mm longer than the ls rods. So the compression will definately go up if used in conjuction with the gsr pistons in the ls block with the ls crank. Don’t know, maybe the valves will hit.
Dunno, maybe he meant the cr will go down if you use the gsr rods/pistons AND crank.
thats all i know

I was wondering if I will have to machine anything when I put in the gsr rods and pistons into my car? Are the gsr rods much stronger then the ls rods? also what would the compression be when i put them in? What about type r pistons, how much compression with those?
i remember hearing that LS rods are beefier compared to GSRs. i dunnoe maybe an old wives tale but das what i heard
BTW: four type lsr, i dont know if i said this before…but nice time
Okay guys,
I was wondering what kinda of modification you would have to do when you put in 94 up gsr rods and pistons? they will fit right? Well if the ls rods are stronger then I should use them right? how will that effect cr?
if you are goin to use gsr Rods you will need a gsr crank…and to use gsr or itr pistons you have to machine the ls rods to fit…like i did with my LS rods to fit my ITR pistons…it gives me around a 10.7-8 with my jg 301s and the ls stoke stroke…i calculated it…
how much will it cost to machine the ls rods and do I have to balance them?
well i pain $60 to have my ls rods machined to fit the ITR pistons…about the crank to balance iam not to sure…but i can get it knife edge for $100
to clear this up.
LS rods are beefier, but they are not stronger than GSR rods. GSR rods have a higher chromoly content than LS, and ITR are even stronger than GSR.
Use whichever rods correspond to your crank. mixing and matching cranks and rods is generally not going to be good, unless you are intimately familiar with building motor, and how/why they work.
Second , US ITR pistons in an otherwise stock LS longblock are going to yield 10.3:1, not 10.7x. JDM ITR pistons will give you the 10.7x :1 CR. And cam size isn’t going to affect static compression ratio. Where do you see any spaces in the CR formula for cam size/duration? They will affect dynamic compression ratio tho, but that’ another discussion. HTH
